Traveling flat mounting means

Abstract

Improvements in textile raw material card machines of the type of a machine that comprises a structure whereupon a horizontal transversal carding cylinder is rotatively mounted, its revolution surface being provided with barbs and operatively related with an upper carding surface that comprises an endless conveyor formed by a plurality of carding "sheets" (i.e., traveling flats) transversally mounted in relation to the forward direction of said conveyor an articulated among each other, said endless conveyor is disposed in such a way that its lower portion copies correspondingly the curvature of an upper circunferential sector of the carding cylinder, the improvements being that in the endless conveyor section that copies the curvature of the circunferential sector of the carding cylinder, the "sheets" ends are mounted on the periphery of a pair of coaxial idler wheels having approximately the same diameter as that of the cylinder and being freely mounted relative to the cylinder shaft.

Having thus described and determined the nature of the present invention and the way to put same into practice, following is claimed as exclusive property and right: 
     
       1. In a textile raw material card machine comprising a structure whereupon a horizontal transversal carding cylinder is rotatively mounted on a shaft, its revolution surface being provided with barbs and operatively related with an upper carding surface that comprises an endless conveyor formed by a plurality of carding sheets transversely mounted in relation to the forward direction of said conveyor and articulated with respect to each other, said endless conveyor being disposed in such a way that its lower portion copies correspondingly the curvature of an upper circumferential sector of the carding cylinder, the improvement comprising a pair of coaxial idler wheels having approximately the same diameter as that of said cylinder, freely mounted relative to said shaft at a central portion thereof and having a periphery engaging said sheet ends for support thereof. PG,11 
     
     
       2. Improvements in a textile raw material card machine according to claim 1, wherein said coaxial idler wheels are mounted relative to bearings associated with said shaft by a dovetail guide and a slider.
